Surface Preparation: The Foundation of a Successful Remodel

A high-quality bathroom remodel always starts with thorough surface preparation. This step often determines the final result and how long the remodel will last without issues. While it may seem simple at first glance, this is where the foundation for success is laid. If preparation is neglected, problems such as loose tiles, cracked finishes, or moisture damage to walls can occur.

The first step is applying a primer to walls and floors. Primer improves adhesion for subsequent layers and reduces the absorbency of the substrate. This step is especially important in new construction or older homes, where surfaces may be uneven or overly porous. Primer is applied to all areas where tile or flooring will later be installed. Proper priming reduces adhesive consumption and ensures even drying of subsequent layers. The cost for this service typically ranges from $0.85 to $1.50 per square meter, depending on the materials used and the condition of the surface.

Next comes waterproofing, which acts as a protective barrier for your bathroom. Its purpose is to prevent water from penetrating the building structure—critical in areas with frequent water exposure such as showers, around bathtubs, sinks, and floor areas. Various waterproofing materials are used, from cement-based coatings to flexible liquid membranes. Waterproofing is applied in at least two coats, and reinforcement tape is used at critical points such as corners and pipe penetrations. The cost of waterproofing generally ranges from $5 to $10 per square meter, depending on the material and application complexity.

Tile Installation: A Balance of Style and Function

After surface preparation, tile installation begins. This is one of the most visible phases of the remodel and has a major impact on the overall appearance of the bathroom. When selecting tiles, it’s important to consider not only design but also technical properties such as slip resistance, water absorption, and chemical resistance.

The cost of tile installation depends on the size and type of tile. For standard formats up to 40 × 40 cm, the price is typically around $29 per square meter. For large-format tiles, such as 60 × 120 cm, the cost can increase to as much as $40 per square meter, as installation requires greater precision and experience.

Grouting is an essential part of tile work. It serves both an aesthetic and a practical purpose by protecting the substrate from water and dirt. Proper grouting helps prevent mold growth and maintains a clean appearance over time. The cost of grouting is approximately $2 per square meter. Various grout types are available, including epoxy grouts, which are ideal for areas with high moisture exposure.

Fixture Installation: Comfort and Practicality

Once tiling is complete, the installation of bathroom fixtures follows—this step defines the overall comfort of the space. Installing a sink and connecting it to water supply and drainage typically costs around $60 per unit. When choosing a sink, consider the faucet type, mounting method, and dimensions suitable for your bathroom layout.

Installing and connecting a toilet usually costs between $80 and $120, depending on whether it is a floor-mounted or wall-hung model and on the complexity of the installation. Wall-hung toilets require an in-wall carrier system, which increases costs but provides a modern, easy-to-clean look.

If you plan to install a bathtub, installation costs generally range from $100 to $150. If the tub needs to be enclosed or tiled in, additional labor and material costs of about $50 to $100 should be expected, depending on complexity.

Shower Area: A Modern Solution for Any Bathroom

Showers are an increasingly popular choice in bathroom remodels due to their practicality, space efficiency, and modern design. Compared to bathtubs, showers offer quicker use, lower water consumption, and better accessibility—especially beneficial for older adults or people with limited mobility. To ensure both functionality and aesthetics, proper floor slope and high-quality waterproofing are essential.

The shower floor is typically sloped at 1–2% to allow water to drain naturally toward the drain. If this step is skipped or done incorrectly, water can pool, leading to mold growth, moisture stains, and damage to tiles or structural elements.

Building a shower area involves several steps: preparing the substrate, creating the slope, applying waterproofing, and installing tiles. Proper integration of the waterproofing system with the drain is critical to prevent leaks. The total cost for this complete process—including waterproofing and tiling—generally ranges from $100 to $200 per square meter, depending on complexity, materials used, and shower size.

In addition to traditional built-in showers, minimalist curbless designs with linear drains are becoming increasingly popular. These solutions are technically more demanding and often more expensive, but they deliver a sleek, modern, barrier-free shower space.

Plumbing Work: The Backbone of a Functional Bathroom

Plumbing work is the backbone of every bathroom. It includes installing new water supply and drain lines, replacing old pipes, and connecting fixtures and faucets. During a remodel, it’s often necessary to replace outdated pipes that may be corroded or unreliable, helping to prevent future issues such as leaks or low water pressure.

In addition to pipe installation, proper slope for drainage lines is essential to ensure smooth water flow. Choosing and installing high-quality valves, filters, and shut-off components also makes future maintenance easier. Investing in quality components ensures long-term reliability and durability.

The cost of plumbing work varies depending on scope and complexity. Average hourly rates typically range from $15 to $25. Larger projects, such as a complete plumbing replacement, may take several days. In some cases, individual tasks—such as installing a faucet, shower set, or trap—are priced separately.
